Highlight certain promotions, usually seasonal, which can push traffic to specific parts of your website.
Sorting, Filtering, and Viewing All
Allow your customers to customize their ecommerce experience. Give them the ability to arrange your category pages as they please; to sort using various criteria like prices, popularity, a-z, etc. Also provide filters where necessary. Many customers do not enjoy clicking through pages of products and having a "View All" option is a good idea.
When a customer visits a particular product page, he or she demonstrates an interest in that type of product. Why not show them other products that either compliment the product being looked at or solve similar problems? This type of feature can keep users on your website for longer and increase the amount of money that each customer spends.
Out of Stock
Just because some products, sizes, or colors go out of stock, does not mean that your customers should have no options. When such an event occurs, allow customers to sign-up to be notified when the product size and color they desired is back in stock. That way they are less likely to go to a competitor and it shows that you care about serving their needs.
Dynamic Shopping Cart
When a visitor adds an item to your shopping cart, rather than taking them straight to the shopping cart, display your shopping cart on the page in a small window that dynamically populates with the product(s) the customer is adding. This way the user experience is smooth and the customer is assured that their products have been added to the cart.
Shipping Cost Calculator
Allow customers to calculate the shipping costs directly from your shopping cart before going through the checkout process. The purpose of this is to avoid having users who leave due to the uncertainty they face going into the checkout process. Since the checkout process is a significant investment of time and effort, many will rather not start the process than find out halfway through that your shipping costs are too high. Instead, give them the ability to find out upfront, to avoid disappointment later. This may also give them the chance to go back and change some of the items in their cart or save them for later.
Once an order has shipped, provide your customers with tracking information so they can feel at ease during the shipment of their order.
Search and Auto-Complete
Give users the flexibility of searching for products that they are interested in. If the search bar suggests results, that will help you sell more by sending traffic to those specific products or categories rather than displaying a general search results page.
For fear of having to wait for another page to load, many customers may not want to click through to view your product pages. Instead, using a quick preview on category pages will provide them with the information they need to decide if they want the product without having to click through to the product page. Just like having secondary calls-to-action, a quick preview option gives users a secondary choice when browsing your website.
Give your customers quick and easy ways to share your product pages with friends and colleagues. Although it is very easy to do this manually, it increases the chances that someone will share a product with a friend if there is an easy-to-use button to do so.
Extensive product details can make the difference between almost making a sale and an actual sale. If a customer cannot find all the information they are looking for regarding a product, they may feel too uncertain about completing their purchase. It is very important to provide all of the information that you have on your products in a clean, concise manner.
Save for Later
Many visitors may add a number of items to their shopping cart without having the intention of actually completing their purchase. Rather than forcing your customers to make the black and white choice of deleting a product from the cart or buying it, allow them instead to save it for later.
Do not use a flat rate or a single rate for shipping. Different customers will want different shipping methods; some will want their products to arrive immediately and others are fine with paying less for slower shipping. Cater to all types of clients to avoid a drop-off in sales due to shipping options.
Clicking the final "Submit Payment" button for many customers can be a stressful moment. Calm their nerves by not only displaying a payment confirmation page, but also sending an email confirming reception of their payment and containing next steps that they should expect.
